To all whom it may concern:

Be it known that I, JOHN B. BENTLEY, a citizen of. the United States, residing at the city of Jamestown, in the county of Chautauqua and State of New York, have in vented certain new and useful Improvements in Bobbin-Shuttles, of which the following, taken in connection with the accompanying drawings, is a specification.

The invention relates to shuttles used in looms for weaving; and the improvement consists in providing an exceedingly simple construction for holding a split spindle in the shuttle shell or weft case so that the spindle is held firmly in position when snapped to place in the shell and may be quickly and easily removed or raised for the removal of the spool or bobbin; and the invention consists in the combination and arrangement of the parts as shown in the drawings and hereinafter described and claimed in this specification.

In the drawings, Figure 1 is a top plan view of the shuttle with the spindle in position therein; and Fig. 2 is a vertical sectional view of the same showing the construction and arrangement of the parts. Fig. 3 is a top plan view of the preferred form of spindle removed from the shell. Fig. 4 is an end elevation of the holding clip 'or bracket for the spindle, said spindle being shown in section within the key-hole shaped open-ended slot into which it is sprung; and Fig. 5 shows preferred views of the holding clip or bracket and the reversible U-shaped spring for tensionally holding the butt of the spindle within the raised end of' said holding clip or bracket; and Fig. 6 is a side elevation of said clip or bracket with the U-shaped spring therein in tensional holding position [against the end of the spindle, said spindle being shown in the partially raised position; and Fig. 7 is an end elevation of the butt of said spindle. Fig. 8 is a top plan view of the butt end of the shell'or weft case with said holding clip or bracket removed showing the crosswise rib and slot therein for one leg of said raised portion of said clip and of said U- shaped spring.

Like characters of reference refer to corresponding parts in the several views.

Thenumeral 10 designates the shell or weft case which is pointed and tipped at each end in the usual manner and has the a w r e g h se l t r b b ie aha The end leg 18 Specification of Letters Patent. Patented Sept, 27, 1921 Application filed November 8, 1920. Serial No.'422,507.

I 11 therein for containing the spindle 12 for bracket or clip 14, which clip 14 is provided with the raised or inverted U-shaped end 15 which fits over the crosswise holding rib 16 of the Wooden shell 10, which rib 16 provides the crosswise slot 17- between the crosswise rib 16 and the end wall of the groove 13.

p of the clip 14 and of the reversible U-shaped spring 19 are inserted in said slot 17 over the rib 16 thereby'firmly holding said clip 14 and the spring 19 within the groove 13. Two screw bolts are preferably provided in the screw holes 20 which firmly fasten the holding clip'or bracket 14 1n position.

The front end 21 of the .clip or bracket 14 open-ended slot 22 therein wardly so that the spindle the same. The slot 22 forms jaws which hold firmly upon the preferably split spindle 12. The split form of thespindle 12 is preferred since it automatically provides the spring holding tension within said rounded portion 23 of the slot 22. 12 is reversible,

ing the same backward toward the cross-.

wise rib 16 and holding the shoulder 26 on the spindle 12 firmly against the inner wall of the vertical end 21 of saidholding clip or bracket 14.

n enlargement 27 is provided on the rounded or outwardly curved side of each of the split portions of the spindle 12 for the bobbin to rest upon and so as to hold. the bobbin firmly in position on said spindle 12. The butt portion'25 of the spindle is preferably square and fits in the square hole 24 in the raised portion 15 of the clip or bracket 14. Saidbody portion has the The split spindle that is, either fiat side. may be placed upward so long as the semi-.

.75 extends upward and has the key hole shaped which opens up- 12 can be sprung downwardly into the rounded portion 23 of rivet 28 through the two parts, .whichparts are curved 0. their adjac t fa es. said point so that they rock slightly near the bowing spring sides of the spindle andare pressed toward one another as shown in dotted outline in Fig. 3. This rocking freedom of movement at the attaching point at the butt of the spindle by means of the rivet 28, which rivet permits said rocking move ment, allows the bowing sides to be sprung inwardly and outwardly with perfect freedom of movement. The square hole 24: and squared butt 25 prevent any turning of said spindle 12, thereby getting out of position or out of the holding clasp within the slot 22.

It is now apparent that the spindle 12 can be raised partially or removed entirely from the shuttle to receive the bobbin or spool, and that said spindle '12 can be quickly and easily inserted or pressed downward into the holding position within the spring clip or bracket 14, the upwardly turned jaws of the end 21 of said clip holding firmly against the spool or cap end, and

that there are few parts to wear or get out of condition in my improved shuttle.

The spindle 12 is made preferably of spring steel semi-circular parts which bow in opposite direction from one another and which are held together preferably at their tip end 29 by the ferrule cap 80 within which said tip ends 29 are firmly attached; The arrangement of the rocking squared contacting ends 25 at the butt of the spindle 12 with the loose rivet 28 extending therethrough permits the free springing action of the split spindle parts as shown in dotted line in Fig. 3. The semi-circularshaped enlargements 27 spring out against the butt of the bobbin, thereby holding'the same firmly in position, and the ferruleshaped cap 30 assists at the other end of the bobbin in holding the same.

I claim as new:

1. In a shuttle, a holding clip having a key hole shaped open-ended slot in its upturned end, in combination with a resilient split spindle having a shoulder thereon to spring said spindle into holding engagement against said upturned end and into said open-ended slot, and means for holding the butt of said spindle.
